You're talking about Mahsa Amini who was murdered by morality police after being arrested for not wearing a hijab, which was already part of a wider trend inside the country.
Iran crushed the subsequent protests by killing 500 people and arresting over 20,000. But amazingly enough, that event appears to have led to more women not wearing the hijab.

We might see a crackdown, there are rumblings from the Iranian gov, but nothing yet.
